True that QURÄN has come down as a guidance for all the mankind, but if to some extent they be void of piety and are not willing to listen and take lesson, how can the scripture, what so ever, profit them? Flowers never grow in a salty soil though it be rained over abundantly. The same is man's farm land of breast. If not clear of obstinacy against efforts to remedy and relieve, nothing can profit him the least! This is why our Lord says: ``THIS BOOK IS A GUIDANCE TO THOSE WHO ARE VIRTUOUS'' 3- (THE VIRTUOUS ARE) THOSE WHO BELIEVE IN THE UNSEEN, AND PERFORM THE PRAYERS, AND BESTOW IN CHARITY A PART OF WHAT WE HAVE GIVEN THEM.
